Hi Adrian,
CC03 does not come in 18x9.5 but 18x9,18x10 and 18x11 (none of these will clear evo8 brembos
CC02 18x9.5+15 needs a 3mm spacer to clear and we can shave it to about +20 but this pushed the rim even further in so it doesn't help with the brake clearances either.
CC02 18x8.5+19 can be shaved to about +25 which is perfect for the evo8, you can run wider tyres like 245/40/18 or 255/35/18 ( will require coilovers, camber and maybe rear guards rolled)
